Los anfípodos talítridos son considerados los principales consumidores de residuos orgánicos en la zona intermareal de playas arenosas ya que retiran grandes cantidades de macrófitos. La cantidad y composición de los macrófitos depositados pueden influir en el consumo y la tasa demográfica de las especies de talítridos. Sin embargo, en las costas con baja contribución de macrófitos, donde la materia orgánica consiste de detrito, fragmentos de algas y plantas vasculares, el comportamiento alimentario de los talítridos es escasamente conocido. En la costa sur de Brasil, el anfípodo Atlantorchestoidea brasiliensis es la especie más abundante de la macrofauna en playas expuestas con escasos restos de algas. Para entender el comportamiento alimentario de esta especie, se realizaron experimentos sobre la preferencia de alimento y las tasas de consumo. La capacidad de alimentarse en la superficie y dentro del sustrato también se examinó. El alimento ofrecido incluyó el cangrejo de arena Emerita brasiliensis, el berberecho Donax hanleyanus, el pez Mugil sp. y el alga Ulva sp., especies que comúnmente comprenden el detrito varado. Los anfípodos adultos consumieron una amplia gama de alimentos. Las especies más consumidas fueron E. brasiliensis y D. hanleyanus, las cuales se consumieron más durante la noche, mientras que Mugil sp. fue el alimento menos consumido durante tanto el día como la noche. En el ensayo de preferencia de alimento, el consumo de algas fue insignificante por lo que se sugiere que los restos de animales son más importantes para la alimentación de esta especie. Los anfípodos prefirieron algas frescas más que algas secas cuando se ofrecieron simultáneamente. Nuestros resultados indican que los talítridos tienen diferente estrategia y comportamiento alimentario según el tipo de material orgánico depositado en la playa. |
